如何修改异常代码并防止终止？

如何解决如何修改异常代码并防止终止？

我遇到了以下代码的问题。我尝试抓取一组通常具有相同结构但有时会发生异常的页面，我正在努力如何在代码中考虑它。目前，代码搜索括在 'strong' 标签中的某些文本，但有时我要查找的文本被括在 'p' 标签中。如何修改代码以便考虑这一点？

我面临的另一个问题是，如果没有找到任何匹配的文本，代码将停止执​​行，而不是跳转到下一页，即继续。任何想法如何处理这个？

#pull strong tags from speech script section
for i in script:
    if i.find('strong') is not None:
        g = "strong"
    else:
        g = 0
    bj.append(g)
#Create list of index position of strong tags
for j in range(len(bj)):
    if bj[j] == 'strong':
      indices.append(j)
#Create list of text from speech script
for k in script:
    x = k.text.strip()
    convo.append(x)
#Create script ID & Participant ID
script_id = counter2
part_id = counter3
#Create index objects to find positions of speech & participant sections
conf_part_index = convo[convo.index('Conference Call Participants')+1:convo.index('Operator')]
try:
    speech_index = indices[0:indices.index(convo.index('Question-and-Answer Session'))]
except:
    try:
        speech_index = indices[0:indices.index(convo.index('Question-And-Answer Session'))]
    except:
        try:
            speech_index = indices[0:indices.index(convo.index('Questions-and-Answer Session'))]
        except:
            speech_index = indices[0:indices.index(convo.index('Question-and-Answers Session'))]
try:
    QA_index = indices[indices.index(convo.index('Question-and-Answer Session'))+1:]
except:
    try:
        QA_index = indices[indices.index(convo.index('Question-And-Answer Session'))+1:]
    except:
        try:
            QA_index = indices[indices.index(convo.index('Questions-and-Answer Session'))+1:]
        except:
            QA_index = indices[indices.index(convo.index('Question-and-Answers Session'))+1:]
